FIELD: chemistry of polymers, chemical technology.
SUBSTANCE: invention describes new liquid silicon-organic polymers of the general formula: A{[R1R2SiO]m[R3C8H17SiO]n[CH3CF3CH2CH2SiO]p[R4(CH3)2SiO0.5]}b (I) wherein A means oxygen atom (O), CH3SiO1.5, C2H5SiO1.5, Si(O0.5)4; R1 and R mean CH3, C2H5; R3 means CH3, C2H5; R4 means hydrogen atom (H), CH3 but if R4 means CH3 then substitutes R1, R2 and R3 can't mean values CH3 or C2H5 simultaneously; m = 4-20; n = 6-32; p = 0, 2, 6, 8; b = 2, 3, 4. Also, invention relates to a method for their preparing. Synthesized compounds show capacity to work in broad interval of temperatures, i. e. from -60°C to 180°C. Polymers show improved low-temperature, viscosity-temperature and lubricating indices.
EFFECT: improved preparing method, valuable properties of compounds.
